9 Dry Bag Essentials for a Day of Stand-Up Paddleboarding

Pushing off from the shoreline on a stand-up paddleboard offers a unique sense of freedom, but a single unexpected wake can flip your board and send your gear to the bottom of the lake. Having a reliable dry bag loaded with the right gear ensures a minor spill does not turn into a ruined phone, a soggy lunch, or a safety emergency. Packing the right essentials keeps you safe, comfortable, and prepared for a full day of paddling.

Choosing the Right Dry Bag for Paddleboarding

Selecting a dry bag for paddleboarding requires balancing storage capacity with the physical limitations of your board’s deck rigging. A bag that is too large becomes a sail in high winds, while a bag that is too small forces you to leave safety gear behind. For a standard day trip, a 15-liter to 20-liter capacity provides the ideal sweet spot for packing extra layers, snacks, and safety gear without overcrowding the nose of your board.

The material and closure style are your primary defenses against water intrusion. Look for heavy-duty, abrasion-resistant fabrics like TPU (thermoplastic polyurethane) or high-denier nylon with welded seams rather than sewn ones. Roll-top closures are the industry standard for a reason: they are incredibly reliable when folded at least three times, and they create a natural carry handle once buckled.

Do not overlook the attachment points on the bag itself. Paddleboarding involves constant motion and occasional splashes, meaning your bag needs secure D-rings or lash loops to anchor it to your board’s bungee system. A bag that slides around on the deck disrupts your balance and risks getting lost if you capsize in moving water.

Dry Bag – Sea to Summit Big River Dry Bag

A premium dry bag acts as the vault for your entire day’s gear, keeping everything from dry clothes to sensitive electronics bone-dry even during a full immersion. When you are miles from your launch point, you cannot afford a cheap plastic bag that cracks along the seams or tears when scraped against a rocky shoreline. The dry bag is the foundational piece of equipment that makes the rest of your paddleboarding gear usable.

The Sea to Summit Big River Dry Bag stands out due to its exceptionally rugged 420D ripstop nylon construction and TPU lamination. This heavy-duty build shrugs off abrasion from sand, gravel, and rough deck grip tape that easily shreds lighter bags. Multiple heavy-duty lash loops (called daisy chains) are welded directly onto the sides, making it incredibly easy to secure the bag flat against your board using straps or bungees.

• Capacity Options: 5L, 8L, 13L, 20L, 35L, 65L
• Material: 420D waterproof fabric with double-stitched, tape-sealed seams
• Best Use: Flatwater paddleboarding, river touring, and coastal expeditions

Before buying, consider the sizing options, though the 20-liter version is generally the most versatile size for a full day on the water. Keep in mind that roll-top bags require at least three full rolls to guarantee a waterproof seal, which slightly reduces the usable vertical space inside. Regularly inspect the buckle and stiffening strip at the roll-top for dirt or sand, as small particles can compromise the seal.

This bag is ideal for paddlers who frequent rocky rivers, coastal waters, or rough lakes where gear gets knocked around. It is not the right choice for ultra-light backpackers who prioritize shaving every ounce, nor is it meant for prolonged underwater submersion like scuba diving.

Waterproof Phone Case – Pelican Marine Active Case

While a dry bag protects your gear during transit, you need instant access to your phone for navigation, emergency communication, and photos without risking water damage. A dedicated, wearable waterproof phone case prevents your lifeline to the shore from slipping into the depths when you take a sudden spill. It keeps your device protected from both direct splashes and the humid, salty air that can corrode sensitive charging ports.

The Pelican Marine Active Case provides military-grade drop protection alongside an IP68 waterproof rating, meaning it can withstand continuous submersion. The clear, touch-sensitive window allows you to operate your phone’s screen and cameras easily, even with wet hands. It features a heavy-duty lanyard and a secure, built-in strap system that lets you lash the phone directly to your life jacket or wrist.

• Waterproof Rating: IP68 (certified up to 3.3 feet for 30 minutes)
• Compatibility: Fits most smartphones up to 6.7 inches
• Key Feature: Detachable lanyard and elastic wrist strap included

Users should note that touchscreens do not register touch inputs underwater due to the conductivity of water, so you must use your phone’s physical volume buttons to snap photos while submerged. Additionally, trapping a hot phone inside a sealed plastic case under direct sunlight can cause the device to overheat. Make sure to slide the phone out during breaks in the shade to let it cool down.

This case is a must-have for paddlers who navigate solo or venture into open water where keeping a phone functional and accessible is a safety requirement. It is not necessary for casual paddlers who prefer to keep their phone completely turned off and tucked away inside the main dry bag.

Microfiber Towel – Nomadix Original Towel

A packable towel is crucial for drying off after an unexpected swim, wiping mud off your feet before stepping back onto the board, or clearing condensation from your sunglasses. Traditional cotton towels are bulky, absorb water like a sponge, and stay wet and heavy inside your dry bag for hours, creating a musty mess. A high-performance microfiber alternative solves these issues by packing down small and drying rapidly.

The Nomadix Original Towel is the perfect companion for paddleboarding because it is made from post-consumer recycled plastic and engineered to be slip-resistant and sand-resistant. Sand shakes right off the tight weave, preventing you from transferring abrasive grit into your dry bag or onto your board’s deck pad. It absorbs four times its weight in water, yet dries dramatically faster than standard cotton.

• Dimensions: 30 x 72 inches
• Material: MicroGrid certified post-consumer recycled polyester
• Key Feature: Sand-resistant weave and integrated hanging loop

Because microfiber absorbs moisture so efficiently, it can develop odors if stuffed wet into a sealed dry bag for days on end. Always hang the towel to dry using its built-in loop as soon as you return to land, or strap it under your board’s deck bungees to dry in the sun while you paddle. It is also quite large, so learning to roll it tightly is essential for saving valuable dry bag space.

This towel is perfect for active paddlers who want a multi-use tool that functions as a towel, a changing wrap, or a beach blanket. It is not suitable for those looking for a plush, fluffy bathroom towel feel, as microfiber has a distinct, flat texture designed strictly for performance and quick drying.

Marine First Aid Kit – Adventure Medical Kits Marine 100

Accidents happen on the water, from scraping your shin on a submerged branch to getting a stray fishhook caught in your hand. Having a marine-specific first aid kit on hand ensures that minor injuries can be cleaned and treated immediately, preventing infections caused by waterborne bacteria. Regular household kits use cardboard boxes and non-waterproof bandages that turn to mush at the first sign of moisture.

The Adventure Medical Kits Marine 100 is specifically designed for wet environments, featuring a water-resistant dry bag outer case with a roll-top closure. Inside, the contents are organized by injury category in clear, waterproof pockets, allowing you to find what you need quickly in a high-stress situation. It includes marine-specific treatments like medication for motion sickness, sterile dressings, and extra-strength waterproof bandages that actually stick to wet skin.

• Capacity: Designed for 1 to 4 people on trips up to 24 hours
• Case Style: Roll-top dry bag with buckle closure
• Key Inclusion: Advanced wound care and motion sickness medication

Before heading out, take the time to open the kit and familiarize yourself with where everything is located, as searching through a new kit during an emergency wastes critical time. You should also check expiration dates on medications annually and replace used items immediately after a trip. While the outer bag is water-resistant, it should still be stored inside your main dry bag for maximum protection.

This kit is ideal for paddleboarders exploring remote lakes, winding rivers, or coastal bays far from medical help. It is unnecessary for casual paddlers who never leave the immediate vicinity of a supervised swim beach or a heavily populated resort dock.

Waterproof Power Bank – Anker PowerCore Solar 20000

Cold temperatures, constant GPS tracking, and searching for cellular signals in remote areas can drain your phone’s battery faster than expected. A dead phone means losing your navigation maps, safety apps, and communication abilities when you might need them most. A rugged power bank ensures you can recharge your phone, action camera, or VHF radio on the go.

The Anker PowerCore Solar 20000 is built for the elements, featuring an IP65 rating that protects it against dust, sand, and heavy splashes. It features a massive 20,000mAh capacity, which can charge a standard smartphone multiple times over a long weekend. The integrated solar panel offers a crucial emergency backup option, allowing you to trickle-charge the battery using daylight when traditional power sources are unavailable.

• Battery Capacity: 20,000mAh / 74Wh
• IP Rating: IP65 (dustproof and splash-resistant)
• Input Ports: USB-C and Micro-USB; Output Ports: Dual USB-A

Keep in mind that solar charging is a slow process meant strictly for emergency backup; you should always fully charge the power bank from a wall outlet before leaving home. To maintain the waterproof seal, ensure the rubber port covers are pressed firmly into place whenever a cable is not plugged in. Store the charger in an easy-to-reach pocket of your dry bag to protect it from direct, prolonged submersion.

This power bank is ideal for all-day paddlers, multi-day campers, and those who rely heavily on GPS tracking apps during their excursions. It is not ideal for casual, short-duration paddlers who stay close to shore and only require an hour or two of battery life.

Floating Sunglasses – Rheos Gear Eddies Sunglasses

The sun’s glare reflecting off the water’s surface can cause intense eye strain, fatigue, and temporary blindness, making polarized sunglasses an absolute necessity. However, standard sunglasses sink like stones the second they slip off your face during a paddle stroke or a fall. Floating sunglasses protect your eyes from harmful UV rays while eliminating the fear of watching your expensive eyewear disappear into the dark depths.

Rheos Gear Eddies Sunglasses are built with a specialized ultralight frame material that allows them to float completely on the water’s surface. They feature premium polarized lenses with dual-sided anti-fog and hydrophobic coatings, which prevent water droplets from drying into distracting mineral spots on the glass. The frames are designed to fit securely during active movement, offering 100% UV protection and a clear view of underwater hazards like rocks or shallow sandbars.

• Frame Material: Ultralight TPX plastic (naturally buoyant)
• Lens Treatment: Polarized with hydrophobic and anti-scratch coatings
• UV Protection: 100% UV400 protection

While these glasses float, they can still drift away quickly in strong river currents or windy lake conditions. Adding a bright, high-visibility eyewear retainer strap can make them even easier to spot and grab if they do fall off. Always rinse the lenses with clean, fresh water after saltwater use, as salt crystals can scratch the specialized coatings if wiped dry.

These sunglasses are perfect for any stand-up paddleboarder who wants high-quality eye protection without the constant anxiety of losing their glasses overboard. They may not suit those who prefer glass lenses, as the lightweight polymer construction is necessary to make the glasses float.

Mineral Sunscreen – Thinksport SPF 50+ Sunscreen

Spending hours on a paddleboard exposes you to double the solar radiation due to sunlight reflecting off the water. A severe sunburn can ruin a trip quickly, while long-term exposure risks skin damage and heat exhaustion. Using a high-quality, water-resistant sunscreen is essential, but it is equally important to use a formula that does not harm the delicate aquatic environments you are exploring.

Thinksport SPF 50+ Sunscreen is a dermatologist-recommended mineral sunscreen that relies on non-nano zinc oxide to block harmful UV rays. It is highly water-resistant (80 minutes), meaning it won’t instantly wash off when you sweat or take a dip in the water. Crucially, the formula is free of biologically harmful chemicals like oxybenzone and octinoxate, making it safe for reef systems, lakes, and rivers.

• Active Ingredient: 20% Non-Nano Zinc Oxide
• Water Resistance: 80 minutes
• Certification: EWG Verified (highest safety rating)

Because mineral sunscreen sits on top of your skin to reflect UV rays, it has a thicker consistency than chemical sunscreens and requires thorough rubbing to blend in. Apply it at least 15 minutes before getting on the water to allow the protective barrier to set properly. Be careful when handling your paddle or board with sunscreen on your hands, as it can make plastic and composite shafts quite slick.

This sunscreen is perfect for environmentally conscious paddlers who need maximum, long-lasting sun protection during active water sports. It is not ideal for those who prefer ultra-light chemical sprays or absolutely refuse any initial white residue on their skin.

Marine Multi-Tool – Gerber Center-Drive Rescue

A paddleboarding excursion can quickly be interrupted by minor equipment failures, such as a loose fin screw, a tangled fishing line, or a torn bungee cord. Carrying a marine-grade multi-tool ensures you can make quick adjustments and emergency repairs right on the water without paddling back to the car. Without a tool, a loose accessory can render your board unstable or unusable.

The Gerber Center-Drive Rescue features a rugged design optimized for emergency situations and wet environments. It includes a one-thumb opening pliers system, a strap cutter for quickly slicing through tangled lines, and a full-size driver that aligns like a real screwdriver for maximum torque. The tools are constructed from high-quality stainless steel, offering excellent corrosion resistance against saltwater and freshwater splashes.

• Blade Style: Fully serrated sheepsfoot safety blade
• Key Tools: Spring-loaded pliers, rotatable carbide wire cutters, strap cutter
• Driver System: Center-axis screwdriver with magnetic bits

Even with high-grade stainless steel, any multi-tool exposed to wet environments requires basic maintenance to prevent rust and stiffness. Always rinse the tool in fresh water after use, dry it thoroughly, and apply a light coat of marine-grade lubricant to the pivot points periodically. Store it in a dedicated sheath inside your dry bag so it does not puncture the dry bag’s inner lining.

This tool is essential for paddlers who use complex boards with multiple mount systems, fin boxes, or fishing attachments. It is unnecessary for casual paddlers using simple, inflatable recreational boards with toolless clip-in fins.

Insulated Water Bottle – Hydro Flask Wide Mouth

Dehydration on the water can creep up quickly due to the combination of physical exertion, sun exposure, and wind. Drinking lukewarm water from a plastic bottle that has been sitting in the sun is unappealing and does little to lower your core body temperature. A high-quality insulated bottle keeps your water ice-cold for hours, encouraging you to stay hydrated and energized throughout your paddle.

The Hydro Flask Wide Mouth features double-wall vacuum insulation that keeps beverages cold for up to 24 hours. The durable 18/8 pro-grade stainless steel construction ensures the bottle can survive drops onto rocky shores or the hard deck of your board without cracking. The wide-mouth design makes it easy to pack the bottle with ice cubes before you launch, and it is compatible with various lid styles, including straw caps for easy drinking while balancing.

• Insulation: TempShield double-wall vacuum insulation
• Material: 18/8 pro-grade stainless steel with BPA-free powder coat
• Cap Compatibility: Wide-mouth straw lid, flex cap, and chug lid

A heavy metal bottle can sink instantly if dropped in deep water, so attaching a lanyard or a silicone boot with a carabiner is highly recommended. Ensure the lid is threaded correctly and tightened fully before tossing it into your dry bag, as a slow leak can dampen your dry gear. Wash the bottle thoroughly after each trip, paying close attention to the rubber gaskets in the lid where mold can hide.

This bottle is perfect for paddlers who demand ice-cold hydration during long, hot days on the water. It is not the best choice for lightweight enthusiasts who prefer collapsible, soft-sided flasks to save space and weight inside their dry bag.

How to Pack and Secure Your Dry Bag on the Board

Packing a dry bag efficiently requires a systematic approach to weight distribution and accessibility. Place heavy, rarely used items like your first aid kit, spare clothes, and the multi-tool at the very bottom of the bag to keep the center of gravity low. Put frequently accessed items like your sunscreen, water bottle, and sunglasses near the top where you can grab them without unrolling the entire bag.

Before sealing your roll-top dry bag, squeeze out most of the excess air, but leave a small cushion of air inside. This trapped air acts as a built-in flotation device, ensuring the bag will float on the water’s surface if it somehow gets disconnected from your board. Once rolled tightly at least three to four times, buckle the clip securely to form a waterproof seal.

Securing the bag to your board is just as important as packing it correctly. Thread your board’s nose bungees through the bag’s D-rings or daisy chains, or use dedicated utility straps to anchor it flat against the deck. Avoid placing the bag too far forward on the nose, as excess weight at the front of the board can cause it to plow through waves rather than glide smoothly over them.

Caring for Your Dry Bag to Prevent Mold and Leaks

A dry bag is a high-performance piece of safety gear, and treating it as such ensures it remains waterproof for years to come. After every trip, especially in saltwater environments, empty the bag completely and rinse both the inside and outside with fresh, clean water. This removes abrasive sand particles, salt crystals, and organic matter that can degrade the fabric and welded seams over time.

Never store a dry bag while it is damp or tightly rolled up, as this creates a dark, humid breeding ground for mold and mildew. Hang the bag upside down with the opening propped wide open in a shaded, well-ventilated area until it is completely dry inside and out. Avoid exposing the bag to direct sunlight for long drying periods, as UV rays can break down the waterproof coatings and weaken the plastic buckles.

Perform a simple leak test before the start of each paddling season. Fill the bag with air, roll it closed, and submerge it in a bathtub or sink while gently squeezing; look for any escaping air bubbles that indicate a pinhole leak. Minor tears or punctures can easily be repaired using a specialized flexible repair adhesive, such as Aquaseal, ensuring your gear stays dry on your next adventure.

Conclusion

Equipping your paddleboard with a well-packed dry bag turns a simple outing into a confident, self-contained adventure. By investing in durable, purpose-built gear and maintaining it properly, you protect your valuable electronics and ensure your safety on the water. With your essentials secured and protected, you can focus entirely on the horizon and the quiet glide of your board.
